Application filed April 20, 1906. Serial No. 312,787.

To all whom it muy concern:

Be it known that l, J'oiiN W. Limoux, a citizen of the United States, residing.:T at Swarthmore, in the county of Delaware and State of Pennsylvania, have invented certain Im rovements in Fluid-M eters, of which the fol owing is a specification.

This 'invention is a tiuid meter having iinproved means for effecting the differential movement of a register or indicator, the in provements com'prisin, l a wheel rotated by fluid pressure under control of an escapement and mechanism coperatiiu;l therewith to operate the register or indicator.

In the drawings, Figure 1 represents an elevation of the lnvention with the casing` removed, Fig. 2 is a to .i plan view show ingl the casing in section, ifig. 3 is ay sectional view taken on the line 3-3 of Fig. 1, and Fig. 4 is a sectional view taken on the line 4 4 of Fig. 1.

The apparatus comprises the base 1 and the closure 2 with the sight glasses 3 and 4 therein.

The base supports the chambers 5 and ti, having their bottoms connected by the tube 7 and their tops connected with the respective tubes 8 and 9 for communicating pressure of, a liquid et the normal and contracted sections of a conduit to a; heavier liquid con- A float 10, in the chamber 6, is suspended by a cord or wire 11 from a` drum or disk 12 which is journaled on a bearing 12 carried by the base, the part 11 working through a small passage in the other Wise closed top of the chamber 6. The float is counter-balanced by a Weight 13 connected by a cord or Wire 14 with the drinn or disk.

AA cam 15 and a pointer 1G are fixed to the drum and afre revolved therewith proportionately to the movement of the float diie to variations in the hei ht of the column of liquid supporting it, t ie latter'varying with variations in the resultant pressure exerted upon' such liquid by the lighter liquid in the chambers 5 and 6. -The pointer travels over the dial 17, supported by the brackets 17', to indicate the rate of How. at any given instunt.

A lever 18 oscillating on the bearings 19 is provided with a. tap et 20 which makes contact with the cam, ue to the action of the levers counter-weight 21. The u ward movement of the tappet is thus varied y the inovcnicnt in thc opposite direction. a stan tional-y arm Q5 willi tlieclutch Z5 preventing the reverse niovcincnt ol tht` disk` A spur wliccl t' is fixed to the disk 24 by a shaft 37 and :ictuatcs a register 'i8 by steps proportional to thc arm of oscillation of the lever 1.8.

To inovc the tappet lever 1S to the limit ot' its stroke away from the cani'` a pitinan or connecting rod "29 with an enlargement 29 on its upper cud plays freely in its npward movement through the end of the lcver and in its downward movement engages the lever so as to carry it against the limit ing stop 22. The pitnian rod is operated by its eccentric pivotal connection 30 with a lspur-Wheel 3l revolving at a regular rute.

To revolve the spur wheel 31 it is geared to a pinion fixedto a vane wheel 33, the pinion and vane wheel revolving,T on the bearing 34. The varies 35 of the Wheel 33 receive the impact of fluid discharge 'oy a nozzle 36 from a vessei 37.

To cause a regular rate of revolution of the vane Wheel., it is subjected to a. regular rate of discharge from the nozzle 3G induced by a uniform head. which is provided hy the discharge into the vessel 37 from a supply pipe 38 and the drip pipe 39 (for the fluid escaping' from the chamber (i) so as to keep this vessel constantly filled. The overfiow from the basin 37 is' received by the basin 40 which tlischaiifes` by the pipe l1 to the waste pipe 4Q, while the discharge from the vane wheel is collected by the catch basin 43 which cmptics into the pipe 42.

To secure the isochronous movement of the register actuating mechanism, the vane wheel 33 has secured thereto a. pin wheel 44 whose pins 45 engage the pallets 46 alternately, the pallets beingr connected with and oscillatingr a pendulum 47 carried by the su port 48, and the revolution of the wheel heilig thus under control of an escapement.

The vane wheel with the mechanism connected therewith may bc used, under other conditions, to measure an irregular How through the nozzle 35 by providing a fixed :uw: of oscillation vfor the lever y18, tus by lixiug the'fuui iu thc requisite position, when thc mcvhuuifuu would opcl'utc to indicate the snm oi' the revolui muxof llic wheel through its vuaious ruler.
